Vectors are generally created using the c() function.Since, a vector must have elements of the same type, this function will try and coerce elements to the same type, if they are different.Coercion is from lower to higher types from logical to integer to double to character.If we want to create a vector of consecutive numbers, the : operator is ver… Using colon operator with numeric data When we execute the above code, it produces the following result − Using sequence (Seq.) An open connection … library("reader"). my_txt <- readLines(paste(path, "/my_txt.txt", sep = "")) write.table(x = print("this is the first line\nthis is the second line\nthis is the third line"), png, jpeg or webp format. install.packages("xlsx") I hate spam & you may opt out anytime: Privacy Policy.
